Gender differences in child and adolescent daily activities : a cross-national time use study

2021

This study used 2009–2015 time-diary data to examine gender differences in daily activities among children and adolescents aged 10–17 in Finland, Spain and the UK ( N = 3517). In all three countries, boys were significantly more involved in screen-based activities and exercising and girls in domestic work, non-screen educational activities and personal care. Gender differences in socializing time were only significant in the UK, with girls socializing more than boys. Gender gaps within countries were largest in domestic work (UK: 60%; Finland: 58%; Spain: 48%) and exercising (UK: 57%; Finland: 36%; Spain: 27%), followed by educational time (UK: 35%; Finland: 34%; Spain: 18%) and screen-bas…

Age affects myosin relaxation states in skeletal muscle fibers of female but not male mice

2018

The recent discovery that myosin has two distinct states in relaxed muscle–disordered relaxed (DRX) and super-relaxed (SRX)–provides another factor to consider in our fundamental understanding of the aging mechanism in skeletal muscle, since myosin is thought to be a potential contributor to dynapenia (age-associated loss of muscle strength independent of atrophy). The primary goal of this study was to determine the effects of age on DRX and SRX states and to examine their sex specificity. We have used quantitative fluorescence microscopy of the fluorescent nucleotide analog 2′/3′-O-(N-methylanthraniloyl) ATP (mantATP) to measure single-nucleotide turnover kinetics of myosin in skinned skel…

Physical activity and sleep profiles in Finnish men and women

2013

Background. Physical activity (PA) and sleep are related to cardiovascular diseases (CVD) and their risk factors. The interrelationship between these behaviors has been studied, but there remain questions regarding the association of different types of PA, such as occupational, commuting, and leisure time to sleep, including quality, duration and sufficiency. It is also unclear to what extent sleep affects peoples’ PA levels and patterns. Our aim is to investigate the interrelationship between PA and sleep behaviors in the Finnish population, including employment status and gender. Methods. The study comprised population based data from the FINRISK 2012 Study. A stratified, random sample of…

Do Epigenetic Clocks Provide Explanations for Sex Differences in Life Span? A Cross-Sectional Twin Study

2022

Abstract Background The sex gap in life expectancy has been narrowing in Finland over the past 4–5 decades; however, on average, women still live longer than men. Epigenetic clocks are markers for biological aging which predict life span. In this study, we examined the mediating role of lifestyle factors on the association between sex and biological aging in younger and older adults. Methods Our sample consists of younger and older twins (21‒42 years, n = 1 477; 50‒76 years, n = 763) including 151 complete younger opposite-sex twin pairs (21‒30 years). Blood-based DNA methylation was used to compute epigenetic age acceleration by 4 epigenetic clocks as a measure of biological aging. Path mo…

Validity of Using Velocity to Estimate Intensity in Resistance Exercises in Men and Women

2020

AbstractThis study aimed to examine the validity of using bar velocity to estimate relative load in squat and bench-press exercises for both young men and women. Twenty-five men and 25 women performed a progressive loading test up to 1-RM in the squat and bench-press exercises, which were repeated after 2-weeks. Relationships between mean propulsive velocity and%1-RM were analysed. A second-order polynomial equation for predicting the corresponding velocity of each percentage of 1-RM was developed for men (validation). This equation was then applied in women (cross-validation). Moreover, a specific equation for women was developed (validation) and was also applied in a sub-sample of women (…

Genetic and Environmental Effects on the Individual Variation and Continuity of Participation in Diverse Physical Activities

2021

INTRODUCTION Participation in diverse physical activities has beneficial health effects. However, little is known on how genetic and environmental factors affect this trait. Thus, we examined to what extent these factors explain participation in diverse leisure-time physical activities from late adolescence to adulthood using a twin study design. METHODS The participants were Finnish twins who reported their participation in diverse leisure-time physical activities at ages 17 (n = 5429) and 34 yr (n = 4246). The number of physical activities engaged in was analyzed using applications of structural linear modeling for twin data. RESULTS On average, the total number of physical activities eng…

Gender-related differences in psychometric properties of WHO Disability Assessment Schedule 2.0

2019

Objective of this study was to investigate the gender-related differential item function of 12-item WHODAS 2.0 amongst patients with chronic musculoskeletal pain. This was a cross-sectional survey study among 1,988 patients at a university Physical and Rehabilitation Medicine outpatient clinic. To assess DIF, WHODAS 2.0 items were dichotomized as `none’ rated by respondents as `0’ versus `any limitation’ rated as `1,2,3 or 4’. The item response theory analysis was used to define discrimination and difficulty parameters of a questionnaire. The probit logistic regression was used to test uniformity of DIF between gender groups. The results of DIF analysis were presented and evaluated graphica…

Associations of Sex Hormones and Hormonal Status With Arterial Stiffness in a Female Sample From Reproductive Years to Menopause

2021

Objective: Loss of sex hormones has been suggested to underlie menopause-associated increment in cardiovascular risk. We investigated associations of sex hormones with arterial stiffness in 19–58-years-old women. We also studied associations of specific hormonal stages, including natural menstrual cycle, cycle with combined oral contraceptives (COC) and menopausal status with or without hormone therapy (HT), with arterial stiffness. Methods: This study includes repeated measurements of 65 healthy women representing reproductive (n=16 natural, n=10 COC-users) and menopause (n=5 perimenopausal, n=26 postmenopausal, n=8 HT-users) stages. Arterial stiffness outcomes were aortic pulse wave veloc…

Miesten juttuja : ammatti-identiteetti miesopettajien kertomana

2015

TIIVISTELMÄ Niskavaara, J. 2015. Miesten juttuja. Ammatti-identiteetti miesopettajien kertomana. Kasvatustieteen pro gradu-tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. Tutkimuksessa tarkastellaan miesopettajan ammatti-identiteettiä, sen olennaisimpia piirteitä ja ammatti-identiteetin muutosta työuran edetessä. Ammatti-identiteetin muuttumiseen vaikuttavat oleellisesti asiantuntijuuden kehittyminen ja tällä hetkellä ajankohtaiset kouluorganisaatioiden kehittämispyrkimykset. Koska tutkimusjoukko koostuu pelkästään miehistä, on tutkimuksessa käsitelty opettajuutta myös sukupuolinäkökulmasta. Tutkimus perustuu miesopettajien omiin kertomuksiin kokemuksistaan työssään ja heidän kert…
